Target Audience:
Intended for neuroradiologists and neuroradiology trainees with varying degrees of experience.

Learning Objective:
Learn and understand the normal anatomy of the external carotid artery
and its branches as seen on flat-panel angiography.

Abstract
The external carotid artery (ECA) and its branches are frequently involved in different
vascular and tumoral pathologies that affect the brain, head, and neck. There are important
anatomic references that cannot be adequately represented on DSA, a technique commonly
used to characterize the ECA. Flat-panel angiography is a 3-dimensional rotational
angiographic technique that uses a flat panel detector to show highly detailed vascular
anatomy and the adjacent bone structures due to its high spatial and contrast resolutions.
We reviewed 119 angiography and flat-panel angiography studies, and described branches
and courses of the superior thyroid, lingual, facial, ascending pharyngeal, occipital, posterior
auricular, internal maxillary, and superficial temporal arteries. DSA is considered the criterion
standard for the study of the vascular anatomy, but we believe that flat-panel angiography
with MPR is a better method to learn and understand, with a multidimensional platform,
the vascular anatomy of the fine branches of the ECA and their relations with the bone
structures of the skull base.
